可重复使用的超声手术器械Reusable Ultrasound Surgical Instruments

技术领域technical field

本申请涉及一种外科手术器械，具体涉及一种可重复使用的超声手术器械。The present application relates to a surgical instrument, in particular to a reusable ultrasonic surgical instrument.

背景技术Background technique

随着微创外科手术的普及，超声刀已经成为一种常规的手术器械。超声刀通过超声频率发生器使刀头以一定的超声频率进行机械振荡，使组织内的水分子汽化、蛋白质氢键断裂、细胞崩解，从而使得组织被切开或者凝固，还可以使血管闭合。超声手术刀使组织切割和凝固止血同时完成，并具有较小的侧向热损伤。With the popularization of minimally invasive surgery, the ultrasonic knife has become a conventional surgical instrument. The ultrasonic knife makes the knife head mechanically oscillate at a certain ultrasonic frequency through the ultrasonic frequency generator, so that the water molecules in the tissue are vaporized, the protein hydrogen bonds are broken, and the cells are disintegrated, so that the tissue is cut or coagulated, and the blood vessels can also be closed. . The ultrasonic scalpel enables simultaneous tissue cutting and coagulation hemostasis with less lateral thermal damage.

超声手术刀系统主要由超声频率发生器、换能器和手术器械组成。其中，超声频率发生器发出振荡电信号，换能器将振荡电信号转换为机械振动，手术器械利用换能器的机械振动对组织进行切割和凝固止血。手术器械通常由刀杆、与刀头(刀杆头部的切割部位)构成夹持结构的夹钳、包围在刀杆外部的套管、握柄及抓持机构组成。刀杆将换能器产生的机械振动传递到刀头；刀头与夹钳配合夹持组织实现切割和凝固止血的功能；套管一方面将刀杆与外部隔离起到保护刀杆的作用，另一方面与夹钳构成连杆机构以带动夹钳的闭合与张开；握柄及抓持机构由医生手部握持，可操作夹钳张开闭合，且有开关可控制超声频率发生器开始或停止输出振荡电信号。The ultrasonic scalpel system is mainly composed of ultrasonic frequency generator, transducer and surgical instruments. Among them, the ultrasonic frequency generator sends out an oscillating electrical signal, the transducer converts the oscillating electrical signal into mechanical vibration, and the surgical instrument uses the mechanical vibration of the transducer to cut and coagulate tissue to stop bleeding. Surgical instruments are usually composed of a cutter bar, a clamp that forms a clamping structure with the cutter head (the cutting part of the cutter bar head), a sleeve surrounding the cutter bar, a handle and a gripping mechanism. The cutter bar transmits the mechanical vibration generated by the transducer to the cutter head; the cutter head cooperates with the clamp to hold the tissue to achieve the functions of cutting and coagulating hemostasis; on the one hand, the sleeve isolates the cutter bar from the outside to protect the cutter bar, On the other hand, it forms a link mechanism with the clamp to drive the closing and opening of the clamp; the handle and the grasping mechanism are held by the doctor's hand, and the clamp can be opened and closed, and there is a switch to control the ultrasonic frequency generator Start or stop the output of the oscillating electrical signal.

目前市场上主流的超声手术刀系统，如CN101035482 B(参考文献1)、CN106028979A(参考文献2)所公开的，其手术器械的套管由外套管和内套管组成，刀杆位于内套管之内。内外套管之间、内套管与刀杆之间的间隙比较小，但在一台手术完成之后，仍然会有一些血液或者组织液进入内外套管之间或者内套管与刀杆之间的间隙，由于间隙非常小且狭长，进入间隙之内的血液或者组织液很难被清洗干净。因此即便手术器械的结构与性能依然良好，也不能被再次重复使用，而只能作为一次性器械来使用，所以其使用成本非常高昂。The mainstream ultrasonic scalpel systems currently on the market, such as those disclosed in CN101035482 B (Reference 1) and CN106028979A (Reference 2), have surgical instruments whose sleeves are composed of an outer sleeve and an inner sleeve, and the knife bar is located in the inner sleeve. within. The gaps between the inner and outer casings, between the inner casing and the cutter bar are relatively small, but after an operation is completed, some blood or tissue fluid will still enter between the inner and outer casings or between the inner casing and the cutter bar. Gap, because the gap is very small and long, it is difficult to clean the blood or tissue fluid that enters the gap. Therefore, even if the structure and performance of the surgical instrument are still good, it cannot be reused again, but can only be used as a disposable instrument, so the use cost is very high.

为了让手术器械能够重复多次使用从而降低使用成本，CN202908793 U(参考文献3)、CN203988246 U(参考文献4)提出了相应的技术方案。CN202908793U(参考文献3)中将套管、刀杆、夹钳设计成一个可更换的组件结构，只能一次性使用，而其它的零部件可以多次重复使用。这样的设计虽然一定程度上降低了使用成本，但因为套管、刀杆、夹钳这些零部件的成本占据了手术器械成本的绝大多数，因此成本降低效果非常有限。CN203988246 U(参考文献4)中采取的技术方案是将套管和夹钳设计成可更换的组件，只能一次性使用，其它零部件包括刀杆都可以多次重复使用，能够有效降低使用成本。但是该技术方案涉及的零部件较多，采用的焊接、螺纹连接工艺也较多，实现起来比较复杂。In order to allow the surgical instrument to be reused many times and thus reduce the use cost, CN202908793 U (Reference 3) and CN203988246 U (Reference 4) propose corresponding technical solutions. In CN202908793U (Reference 3), the sleeve, the cutter bar, and the clamp are designed as a replaceable component structure, which can only be used once, while other components can be reused for many times. Although such a design reduces the cost of use to a certain extent, the cost reduction effect is very limited because the cost of parts such as sleeves, cutter bars, and clamps account for the vast majority of the cost of surgical instruments. The technical solution adopted in CN203988246 U (Reference 4) is to design the sleeve and the clamp as replaceable components, which can only be used once. . However, this technical solution involves many parts and adopts many welding and thread connection processes, which is more complicated to implement.

As shown in FIG. 2 , the reusable ultrasonicsurgical instrument 3 includes acannula assembly 31 , aknife bar 5 , abase 32 and a clampingdrive assembly 71 , thebase 32 is disposed at the distal end of thehandle 8 , and the Thesleeve assembly 31 can be detachably connected to thebase 32 and the clampingdrive assembly 71 . Saidcannula assembly 31 includes aclamp 4 at its distal end, anouter cannula 61 and aninner cannula 62 . The proximal end of theclamp 4 is provided with tworotating shafts 41 and 42 , wherein the rotatingshaft 41 is rotatably connected with the distal end of theouter sleeve 61 , and therotating shaft 42 is rotatably connected with the distal end of theinner sleeve 62 . Theinner sleeve 62 is installed outside thecutter bar 5 , theouter sleeve 61 is installed outside theinner sleeve 62 , and both theouter sleeve 61 and theinner sleeve 62 are coaxial with thecutter bar 5 . Through the above arrangement, when theouter sleeve 61 is fixed, the rotatingshaft 41 is also fixed, and theinner sleeve 62 is pulled back and forth along the axis of thecutter bar 5 to drive the rotatingshaft 42 to move back and forth, so that theclamp 4 is rotated around the rotatingshaft 41 to achieve The opening and closing between theclamp 4 and the cutter head.

套管组件31可向着刀杆5轴线的远端方向从基座32及夹持驱动组件71拆卸，也可向着刀杆5轴线的近端方向安装在基座32及夹持驱动组件71上。这样的功能主要是通过第一可拆卸结构33及第二可拆卸结构34实现的，其中，第一可拆卸结构33是外套管61与基座32之间的连接结构，第二可拆卸结构34是内套管62与夹持驱动组件71之间的连接结构。所述基座32相对于握柄8在刀杆5轴线方向的运动被固定，夹持驱动组件71与抓持机构7连接并由抓持机构7驱动沿着刀杆5轴线方向来回运动。因此当外套管61被第一可拆卸结构33连接到基座32上，内套管62被第二可拆卸结构34连接到夹持驱动组件71上之后，夹持驱动组件71可带动内套管62相对于基座32沿刀杆5的轴线方向来回运动，从而带动夹钳4相对于刀杆5的头部张开或者闭合。Thesleeve assembly 31 can be detached from thebase 32 and the clampingdrive assembly 71 toward the distal direction of the axis of thecutter bar 5 , and can also be installed on thebase 32 and the clampingdrive assembly 71 toward the proximal direction of the axis of thecutter bar 5 . Such functions are mainly realized by the firstdetachable structure 33 and the seconddetachable structure 34 , wherein the firstdetachable structure 33 is the connection structure between theouter sleeve 61 and thebase 32 , and the seconddetachable structure 34 It is the connection structure between theinner sleeve 62 and the clampingdrive assembly 71 . The movement of the base 32 relative to thehandle 8 in the axial direction of thecutter bar 5 is fixed, and the clampingdrive assembly 71 is connected to thegripping mechanism 7 and is driven by thegripping mechanism 7 to move back and forth along the axial direction of thecutter bar 5 . Therefore, after theouter sleeve 61 is connected to thebase 32 by the firstdetachable structure 33 and theinner sleeve 62 is connected to the clampingdrive assembly 71 by the seconddetachable structure 34, the clampingdrive assembly 71 can drive theinner sleeve 62 moves back and forth relative to thebase 32 along the axis of thecutter bar 5 , thereby driving theclamp 4 to open or close relative to the head of thecutter bar 5 .

参见图2，根据本申请第一种实施方式的可重复使用的超声手术器械中，第一可拆卸结构33由基座32上的光孔333、设置在外套管61近端的螺纹孔331及螺栓332组成。螺栓332穿过光孔333拧紧在螺纹孔331上，这样外套管61与基座32在刀杆5的轴线方向与周线方向便被约束在一起。本领域技术人员容易想到，也可以光孔333设置外套管61近端，而将螺纹孔331设置在基座32上。Referring to FIG. 2 , in the reusable ultrasonic surgical instrument according to the first embodiment of the present application, the firstdetachable structure 33 is composed of anoptical hole 333 on thebase 32 , a threadedhole 331 provided at the proximal end of theouter sleeve 61 , and 332 bolts are formed. Thebolts 332 pass through the light holes 333 and are fastened to the threadedholes 331 , so that theouter sleeve 61 and the base 32 are bound together in the axial direction and the circumferential direction of thecutter bar 5 . Those skilled in the art can easily imagine that the proximal end of theouter sleeve 61 may also be provided in thelight hole 333 , and the threadedhole 331 may be provided on thebase 32 .
